because I'm bored i feel like explaining missingo
in short, missingo was the data of the old guy's avatar when he showed how to catch a Pokemon, the developers needed a place to store it where it couldn't pop up in battle, so they chose the city file (no grass, no wild Pokemon) well the glitch happens when you are surfing the side of cinnabar because you are in a city but on a patch of grass, technically. I guess it tried to fix it by compiling other data either leftover or hidden forming the missingo glitch in whole (and no, i do not know about the 6th infinite item part) btw +2

the speed of sound is about 1150 feet per second (at sea level(dependant on temperature)) so if pidgeot flies at mach 2 that means it flies at about 2300 feet per second at sea level (Dependant on temperature)
